"Ahw, HALL. MACHINE FOR ORUSHING ORE, 6w.
UNITED STATES PATENT OFFICE.
ALEXANDER W. HALL, OF NEW YORK, N. Y.
Specification forming part of Letters Patent No.47.297. dated April 18, 1865. i
To all whom it may concern Be it known that I, ALEXANDER W. HALL, of the city, county, and State of New York, have invented a new and lmprovedMachine for Breaking or Grushin g Ore, Rock, and other Hard Substances; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which-'- Figure 1 is a side View of the machine. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a plan of the same. Fig. 4. is a longitudinal vertical section of a modification of the same.
Similar letters of reference indicate corresponding parts in the several figures.
This invention relates to the employment, for breaking or crushing ore, rock, stone or other hard material, of a horizontally-morn] g direct-acting stamp and a stationary upright abutment, having the upper parts of their faces convergent and the lower parts parallel. or nearly so; and it consists in operating such stamp by means of an eccentric or crank at its rear end acting in concert with a sliding journal-box near the head, whereby I obtain a more effective crushing action than is obtained by placing the crank or eccentric near the head of the stamp with-a guide at the rear end. as will be hereinafter fully explained.
'A A 13, Figs. 1, 2 and 3, is the frame of the machine, composed of a single casting, having upright parallel sides A A, connected at one end by the abutment B. This frame is to be placed on and secured to a suitable bed-- piece or stand of wood or iron. The abutment B is made with the lower part, a, of its inner or working face of plane form and upright, and its upper part, b, of plane form and loping outward in an upright direction.
U D, Figs. 1, 2, 3, is the horizontal directacting stamp made of cast-iron, and having its head 0 fitted to slide freely between the parallel sides A A of the frame toward and from the abutment B. This head has its working-face a b, which is opposite the working-face a b of the abutment,-of a form correspondin g with that of the said face a 1), except th'atthe upper part, a slopes in an opposite direction to that of the part a of the. said face a b, so that the said parts a a combine with the sides A A of the frame to form a hoppershaped apartment, having a wide mouth for the reception of the ore or other material to be broken or crushed. The stamp C D has. formed on each side in line with each other,
and at a short distance in rear of its head 0, two gudgeons, c c, the journals of which are fitted to boxes d d, which are arrangedto slide horizontally in guide-slots d d, provided in the sides A A of the frame, and the rear portion D of the stamp has itsextremit-y constructed and fitted up to form a journal-box,
e, to receive an eccentric wrist, f, of short throw, constructed or provided upon'the horizontal rotary shaft E of the machine,
whichis fitted to work in fixed journal-boxes in the sides A A of the frame. The journalbox 0 is fitted with wedges g g in .front of i and behind its lining-piecesior the purpose of adjusting its bearing toward. or from the headO of the stamp, and. thereby regulating the distance to which the face a. b of the stamp shall approach the face a Z of the abutment in the horizontal reciprocating mov,c-
ment of the stamp'toward and from the abutment, which is produced by therevolution of the wrist f oft-he shaft E, thereby regulating the smallnes of fineness of the particles into which the material is brokenor crushed.
The operation of the maehice is as follows:
The lumps of ore or other material are fed into the hopperdike apartment formed between the upper portions, a, a, of the working-faces of thestamp and stationary abutmeniawhile the stairiphas a rapid horizontal reciproca. ting movement directlyor bodily toward and from the abutment imparted to it by the rapid revolution of the eccentric wrist f, and the lumps descending in the widening space formed betwen theportions a a. of the working-faces, every time the stamp retires from the abutme it with the movement of the said eccentric wri t, are broken smaller by every approach of the stamp toward the abutment, until they drop into the spacebetween the lower portions, b b, of the working-faces, where they are caught by, the said faces, approaching each other in parallel positions in the next revolu;
tioinof the eccentric wrist, and so further broken or crushed to the required size or degree of fineness, after which the material drops from between the abutmentand stamp the next time thela-tter retires from the former, and is received in a suitable receptable.
The vertical length or height of the lower portions, 1) b, of the faces of the abutment and stamp which come nearly together in vertical posi ti 011's, must be proportioned to the velocity of the revolution of the shaft E, according to the natural law of falling bodies, that the material may not fall between the said portions of. the faces without being, crushed. By maklag the height of the said faces not less than seven inches, when the shaft makes three hundred revolutions per minute, the material cannot fail to be caught and broken or crushed at least once between the said portions of the faces.
The parallel worliing-fac0$fwhich need. not
have more than one-quarterbf an inch motion,
can be adjusted to come so nearly together that fragments of ore or stone which have been previously reduced sufficiently, by the convergent faces of the stamp and abutment may be'crushed to tlonr, which is the reat advantage of these faces, in combination with and placed below the convergentfaces of the stamp and abutment, as explained.
By the arrangement of the eccentric or crank at the rear end of the stamp and the sliding journatbox rear the head, I avoid the too great vertical movement, which is occasioned by the arrangement of the eccentric near the head of the stamp, and which wears out the faces of the stamp and abutment, and at the same time I obtain a more eiiective crushing operation by the powerful leverlike action of the stamp produced by the eccentrio, such action, with the crank rotating in the direction of the arrow shown in Figs. 1. and .2, causing the space between the parallel faces a a of the stamp and abutment to commence closing at the bottom and close gradually upward as the stamp approaches the abutment, and thereby causing the crushing action to be extended through a greater portion of the revolution of the eccentric than it the stamp had a strictly rectilinear motion. I'he same movement may be obtained by substitutin g a cranked rock-shaft for the gudgeons c c aml sliding boxes (I (Z, the journals of the said rock-shaft working" in fixed boxes in the sides of the frame and its crank-wrist fitting a box or bearing provided in the stamp.
The workingfaces a b and a b of the abutment and stamp should preferably be composed, as represented, of independent plates of frankllnite iron, which from its hard character renders it especially suitable for operating on hard materials. These plates are bolted to the abutmeii tand stamp in such manner by screw-bolts i i that when worn out they may be removed and replaced by new ones.
Fig. 4 exhibits a longitudinal view ot'a modI- fication of the invention, the parallel portions b b of the faces at and a I) being arranged obliquely to the direction of the reciprocating motion of the stamp instead of perpendicular thereto. The object of this arrangement is to obtain a grinding;v action between the said portions of the faces. as well as a crushing action. \Vhen this oblique arrangement is adopted, it is desirable to use in the guideslots (1 indie-rubber packing-pieces 41 the said pieces being arranged above or below the box (Z, according to the direction of the obliqnity of b b. The object of these packingpieces is to enable the surface I)" to slide to some extent after it has come close against I). This partial sliding or grinding of the two parallel faces, if desired, can be more effectually accomplished by another modification of imyinvention, as shown in Fig: 6, when the eccentric wristfis arranged near the head of the stamp and the sliding journal-box at the back end thereof.
That I claim as myinvention, and desire to secnreby Letters llatent, is-
The combination of a horizontallymoving direct-action stamp and a stationary abut.- ment having'theupper parts of their working-faces convergent and the lower parts thereof parallel, when the movement of such stamp is produced by an eccentric at the rear end of the stamp acting in concert with a sliding journal-box near the head of the stann'), substantially as aml for the purpose herein specified.
